System CPU Usage

What does the System CPU usage mean?
I recently downloaded a widget for my dashboard that monitors CPU usage. I was surprised to find that most of the time the CPU usage was right up at 100% being split about 40-60 between "User" and "System" respectively with 0-2% designated as "Idle". Does this mean that my processor is maxing out all the time? I have a 1.33 GHz PowerPC G4 with 1GB DDR SDRAM, and it seems to be running fine.
I would have expected to see most of my CPU usage percentage being designated as idle, as I can't imagine I am using more than 40% very often. What does it mean when it says that "System" is taking up most of my CPU power?
